This book was released on 2012-12-06 with total page 426 pages. Available in PDF, EPUB and Kindle. Book excerpt: Masters Theses in the Pure and Applied Sciences was first conceived, published, and disseminated by the Center for Information and Numerical Data Analysis and Synthesis (CINDAS)* at Purdue University in 1957, starting its coverage of theses with the academic year 1955. Beginning with Volume 13, the printing and dis semination phases of the activity were transferred to University Microfilms/Xerox of Ann Arbor, Michigan, with the thought that such an arrangement would be more beneficial to the academic and general scientific and technical community. After five years of this joint undertaking we had concluded that it was in the interest of all concerned if the printing and distribution of the volumes were handled by an international publishing house to assure improved service and broader dissemination. Hence, starting with Volume 18, Masters Theses in the Pure and Applied Sciences has been disseminated on a worldwide basis by Plenum Publishing Corporation of New York, and in the same year the coverage was broadened to include Canadian universities. All back issues can also be ordered from Plenum. We have reported in Volume 38 (thesis year 1993) a total of 13,787 thesis titles from 22 Canadian and 164 United States universities. We are sure that this broader base for these titles reported will greatly enhance the value of this impor tant annual reference work. While Volume 38 reports theses submitted in 1993, on occasion, certain uni versities do report theses submitted in previous years but not reported at the time.

Book excerpt: The group of plants known as 'peppers' is diverse, containing types that contribute to the fresh and processed food markets as well as varieties that are used in pharmaceuticals and other non-food commercial products. Peppers originally developed in tropical regions, but are now grown and used in every country where it is possible to grow them, including in areas where production is difficult. This book examines peppers from historical, genetic, physiological and production perspectives, following the development of the cultivated crop from the wild type. Diverse examples of pod types and thei.

Available in PDF, EPUB and Kindle. Book excerpt: Today, most growers use chemical weed management programs; however, a sole reliance on herbicides will place more resistance selection pressure on the weeds to which the herbicide is being applied. As herbicide resistance continues to grow and rob growers of yield, alternative weed control options are being sought to create complex integrated weed management programs to prolong the use of effective herbicides. Harvest weed seed control (HWSC) is a non-chemical practice that has been widely adopted in Australia due to herbicide resistance problems. In most cases, herbicide-resistant weeds that survive applications of herbicides produce viable seed that pass through the combine during crop harvest. HWSC focuses on lowering the soil seedbank by targeting weed seeds that pass through a combine at harvest. Experiments were conducted at the University of Arkansas in 2014 and 2015 to test the efficacy of HWSC on weeds in a soybean production system. Palmer amaranth, which has been deemed the most troublesome weed in the U.S., retains better than 97% of its seed at crop maturity, making it a viable option for seed capture and destruction during harvest. The efficacy of narrow-windrow burning was tested on two small- and large-seeded grass and broadleaf weeds (Palmer amaranth, barnyardgrass, johnsongrass, and pitted morningglory). All seed exposed to narrow-windrow burning treatments were killed. These data suggest that integration of HWSC into current weed management programs in soybean will be a valuable asset to lowering the soil seedbank and ultimately lowering the resistance selection pressure that is placed on herbicides due to lower weed densities.

Download or read book Weed Management Yield and Economic Return on Investment of Six Soybean Systems in Conventional and No till written by Matthew C. Geiger and published by . This book was released on 2018 with total page 216 pages. Available in PDF, EPUB and Kindle. Book excerpt: Shifts toward herbicide resistant weed populations in row crop agriculture is a widespread epidemic. Sequential applications of EPSPS synthase-inhibitors, acetolactate synthase-inhibitors, and other herbicide site-of-action groups, have led to the selection and spread of herbicide-resistant weed biotypes (Powles, 2008; Tranel and Wright, 2002). New soybean systems with resistance to auxin herbicides, along with proprietary herbicide formulations, have been developed to control these herbicide-resistant weeds in soybean production. These new technologies will be compared in both conventional- and no-till with technologies which have been available for several years, in the aspects of weed control, yield, and economic return on investment (EROI). In both 2016 and 2017, when using preemergence (PRE) followed by postemergence (POST) herbicide programs, there were few differences in weed control between the six soybean systems. Adequate grain yield was provided by all soybean systems when proper herbicide programs were used. EROI was the highest when optimum yields were achieved, regardless of treatment cost.

This book was released on 2022 with total page 0 pages. Available in PDF, EPUB and Kindle. Book excerpt: Integrated weed management and herbicide application practices were assessed in field and greenhouse studies to improve weed control in herbicide-resistant soybeans (Glycine max (L.) Merr.) grown in Kansas. The field study was conducted to evaluate weed control, soybean yield, and profitability in two herbicide-resistant soybean systems and two row spacings. 2,4-D-, glyphosate-, and glufosinate- resistant (Enlist E3) and isoxaflutole-, glyphosate-, and glufosinate- resistant (LLGT27) soybeans were planted in 38- and 76-cm row spacing for four site-years. Three herbicide treatments were evaluated in each system: pre-emergence herbicide only (PRE), PRE followed by early post-emergence (POST), and POST plus overlapping residual (POR). Weed control was evaluated every 2 weeks after PRE application through R7 soybean. Weed biomass was collected before POST applications and at R7 soybean. Soybean yield was recorded at harvest. Data were subjected to analysis of variance and means separation. In Ottawa during 2020, POST and POR treatments resulted in ≥ 99% control for all species four WAT, while PRE resulted in ≥ 84% control. Similarly, control at Ashland Bottoms was ≥ 90% for POST and POR treatments, while PRE resulted in 7% for isoxaflutole- 62% for 2,4-D-resistant soybeans. All treatments resulted in ≥ 95% control at Scandia in 2021. Row spacing had a minimal effect on weed control and mixed results for yield. In the greenhouse study, the objective was to determine the effect of herbicide combination, optimize carrier volume, and evaluate weed height on weed control. Co-applications of combinations of 2,4-D choline, glyphosate, and glufosinate were applied in carrier volumes of 93-, 140-, and 187- L ha−1to 5-, 10-, and 20-cm Palmer amaranth (Amaranthus palmeri S. Watson) and large crabgrass (Digitaria sanguinalis L.). Visual ratings and above ground biomass were collected four weeks after treatment. Water-sensitive paper was also sprayed with the same herbicide combinations and carrier volumes to evaluate differences in spray coverage. Data were subjected to analysis of variance and means separation. Carrier volume did not affect Palmer amaranth or large crabgrass control. Control of 5-, 10-, and 20-cm Palmer amaranth was 100%, ≥ 91%, and 6.7 to 79%, respectively, and variation was caused by the herbicide combinations. 2,4-D plus glyphosate provided the greatest Palmer amaranth control. Large crabgrass control pooled for both experiments was ≥ 82% when treatments were applied at 5 cm, but control of 10- or 20-cm large crabgrass was reduced to 51 to 56%. There was a carrier volume by herbicide co-application interaction for the number of droplets deposited and percent area covered on water-sensitive paper. Co-applications containing glufosinate had more droplets than those not containing glufosinate. 2,4-D plus glyphosate had the smallest percent area covered, compared to the other herbicide co-applications. Data from the field study confirms that two-pass herbicide programs are superior to PRE- only programs, regardless of the inclusion of a layered residual herbicide. However, this research did not evaluate the impact of layered residual herbicides on weed seed production, which is crucial for long-term weed management. Results from the greenhouse study suggest that under ideal conditions, carrier volume is less important than herbicide combination and weed size for control of Palmer amaranth and large crabgrass.
